Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.
For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less. To get an accurate reading of a battery''s state of charge, you need to use a battery tester or multimeter that takes into account the battery''s type and voltage characteristics.
